SHAFT-HANGER..

Specification of Letters Patent. Patented May 20, 1919.

Application filed March 15, 1918. Serial No. 222,669.

To'aZZ whom it may concern.-

Be it known that I, JAcoB L. SPARLING, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented new and useful Improvements in Shaft-Hangers, of which the following is a specification.

This invention relates to a shaft hanger and one object is to provide a hanger by the use of which a shaft may be properly mounted with reference to a supporting structure, regardless of the exact position of the elements of that structure, the hanger providing all necessary adjustments.

A further object is to provide a hanger comprising a main frame including guides and a plurality of yoke members slidably mounted with reference thereto and adapted to be secured in any adjusted position and to mount a box or bearing proper.

A further object is to provide in connection with mounting means of the character indicated, a bearing box comprising a plurality of separable box members and an inner shell comprising a. plurality of separable members, with means for adjusting the position of the members of the shell and for adjusting the bearing proper within a yoke member or a plurality of yoke members.

- A still further object is to provide a bear ing box including a plurality of members and a shell mounted therein and spaced therefrom, said shell surrounding the shaft and providing for the distribution of lubricating material throughout the space within the box and through channels or apertures provided in the members of the inner shell, whereby said lubricating material is constantly fed to the surface to be lubricated.

A still further object is to provide in connection with a box specified, means for securing the separate members of the box and providing a grease tight connection.

In the accompanying drawings:

Figure 1 is a view in side elevation.

Fig. 2 is a view in vertical section.

Fig. 3 is a section on the line 33 of Fig. 1.

Fig. 4 is a Fig. 1.,

Fig. 5 is a plan view of a box element.

Fig. 6 is a plan view of a section of an inner shell to be located within the box.

section on the line H of The frame of the hanger is designated 10 and includes parallelly arranged members 11 and 12 connected by a transverse member 13, members 11 and 12 being connected at their opposite ends by means of a trans verse member, or yoke 14- detachably secured and held in position by bolts'15 and nuts 16. Members 11 and 12 areprovided with inwardly extending guides 17 these guides being providedqwith apertures 18 permitting the slidable member or members described below to be placed in any desired position lengthwise of the members 11 and 12 to be secured inthat position by means of bolts 19 and 20 passing through the apertures 18.

A plurality of slidable yokes are mounted between the guides 17, these .yokes being designated 22 and 23 and being provided with apertures at the points shown for the accommodation of adjusting bolts 24 carrying jamb nuts 25. v

Each yoke 22 or 23 is provided with a plurality of laterally extending ears 26 spaced apart and cooperating with the guides 17 The surfaces of members 26 are flush with the meeting edges of the yoke members, these surfacesbeing channeled at 28 and providing transversely extending apertures through which bolts pass for securing the yokes in adjusted position with reference to the guides. Adjacent to the ears 25 and 26 are laterally extending members '31 and 32 spaced apart and provided with apertures or bores33 through which bolts 34 pass, these bolts securing the yoke members in position with their meeting edges 35 in contact.

The box in which the shaft is mounted is located as shown with reference to the yoke members and is held in adjusted position by means of devices 24: above specified. The box comprises a plurality of members cylindrical in form and including outstanding portions which encircle the shaft, these portions last named being designated i0 and 41 and the box members proper being designated 42 and l3. Each box member carries a boss 4% centrallyilocated and having a concave surface for engagement with the tapered ends ofthe adjusting devices above specified. -One of the box members includes a plug'connection 45 permitting the box to be filled with lubricating material. --A :plurality of bosses 4:6 located near the ends of the box provide for set screws for holding the inner shell 47 in position. The inner shell includes a plurality of semicylindrical members directly engaging the shaft containing the Babbitt metal, these members being provided with apertures through which lubricating material may pass from the space or chamber 48 between the inner shell and the box proper. The entire space within the box, including that actually occupied by the inner shell is to be filled with lubricant and this material will be forced inwardly toward the shaft, to lubricate the bearing surface at all times. A spacing member 40 is provided on each side of each section of the inner shell and serves to space the latter from the box proper. One section of the inner shell is provided with a boss .50 having a concave surface engaging a convex surface or boss 51 projecting into the shell, and adjustment between the sections on the inner shell is effected by turning the set screws 52 heretofore mentioned. A gasket 53 prevents grease from passing out of the side of the box.

The semi-cylindrical members 40 and 4:1 of the oppositely located box members cooperate to form a sleeve encircling the shaft, and'this sleeve in turn encircled by an outer detachable sleeve 55 comprising a plurality of semicylindrical members 56 and 57 having cars 58 formed thereon and said ears being connected by means of bolts or screws 59.

This sleeve last named is provided with a reduced portion 60 at the outer end for the accommodation of a felt washer or the like 61 engaging the end portion of the members 40 and ll constituting the sleeve first named.

In the construction described provision is made for unusually efiicient lubrication, and for a large variety of adjustments, making it possible to employ the hanger and box in any desired position and to take up wear at any time.

lVhat is claimed is:

1. In a device of the class described, a frame including a plurality of parallel guides, a plurality of yoke members operable between said guides, means for securing the yoke members in various adjusted positions with reference to the guides, a box constituting a bearing, and means for adjustably mounting the box within the yoke members.

2. In a device of the class described, a frame comprising a plurality of parallel guides, a plurality of yoke members reversely arranged with reference to each other and connected with the guides, guiding means carried by each of said yoke members, the guiding means on the oppositely located members being in alinement and 00- Copies of this patent may be obtained for five cents each, by addressing the Washington, D. 0.
